The earth's atmosphere is divided into three separate layers: the troposphere,
The troposphere is the region of the atmosphere where virtually all weather
phenomena take place. In this region, RF energy is greatly affected.
The stratosphere has a constant temperature and has little effect on radio
The ionosphere contains four cloud-like layers of electrically charged ions,
Ground waves and sky waves are the two basic types of radio waves that
transmit energy from the transmitting antenna to the receiving antenna.
